The global market for Train Control and Management Systems (TCMS) is projected to reach US$3.6 billion by the year 2027, trailing a post COVID-19 CAGR of 6.4% over the analysis period 2020 through 2027. Train Control Management System (TCMS) represents an advanced control system that controls and manages flow of information between trains and sub-systems like air conditioners or doors. Acting as the brain, the system controls and optimizes all activities and functions to ensure enhanced efficiency and passenger safety. TCMS leverages sophisticated electronics platforms intended to support programming in various open languages in line with established standards. While the initial TCMS were designed to transmit and display fault data of onboard equipment, the systems have undergone significant advancements over the years with the current systems offering not only powering and braking commands during train operation, but also commands for passenger information, air conditioning, and other service equipment. Over the years, transmission speeds of the train backbone network used by TCMSs to send information between trains has increased along with the expanding functional requirements. The pressing need to cut transport emissions continues to be a major driver behind transition of freight and passengers toward rail. Guidelines to protect the climate are bound to play a positive role in supporting rail travel.

The Green Deal climate protection program announced by the European Commission specifies around 90% reduction in carbon emission associated with the transportation industry by 2050. Similar measures across other regions are slated to facilitate migration towards rail, requiring countries to improve the infrastructure. In addition, the decision of various airlines to abandon short-haul flights as well as collaborate with rail is expected to pave way for long-distance, high-speed trains over the coming years. Moreover, rail operators are likely to further reduce their carbon emissions through electrification and switching toward alternative drive options like hydrogen and battery. Railways represent one of the most energy-efficient transport modes, accounting for about 9% of global motorised passenger movement and 7.5% of freight. Railways account for about 3% of transport energy use. Over the years, the urban and high-speed rail infrastructure has expanded significantly laying the basis for efficient, low-emissions transport system in cities. Passenger rail travel is considered to be the least energy- intensive of all motorised transport modes. Against the intense pressure to curb gas emissions governments in various countries are opting for railway systems displacing more emissions-intensive modes such as cars, trucks and airplanes. The UIC International Union of Railways is also striving to attain carbon neutrality by 2050, in response to the Sustainable Development Goals (SDG) set by United Nations and EU Green Deal challenges.

The negative impact of increasing emission of greenhouse gases and rising air pollution on the public health and climate change is prompting government agencies to enforce stringent rules pertaining to reduction in carbon emissions. Environmental regulations and norms across mature markets like Europe along with emerging economies are anticipated to drive the significance of railways. Rail transportation is known for lower level of carbon emissions in comparison to other modes of transport.The EU requires all member states to focus on reducing greenhouse gas emissions by 40% from the 1990 levels by the year 2030. Moreover, the 'Carbon Offsetting and Reduction Scheme for International Aviation' (CORSIA) specified by International Civil Aviation Organization's (ICAO) is intended to ensure that aviation carbon emissions do not exceed the 2020 levels. The use of trains for travel also holds potential to considerably reduce carbon emissions by 5 million tons through the period. The EC is promoting rail travel as a low-carbon transport mode through several initiatives. The need to meet ambitious objectives related to energy usage and carbon emissions in 2030 and 2050 is likely to propel the adoption of TCMS in the railways sector. The market will also benefit from the development of rail infrastructure. There are more than 11,690 km of high-speed rail lines under construction, enabling the global network to expand by 25% over the next five to six years. However, China is anticipated to claim just 50% of this expansion as it moves towards full deployment. Countries such as South Korea, Turkey, Spain and Switzerland are building their network and even extending it to neighboring countries. Some of the major developments associated with new lines include the UK's HS2 line that represents the most expensive line per km as well as the Basque Y that encompasses 44 viaducts and over 100km of tunnels. In addition, the Lyons-Torino tunnel spanning over 50km and the Californian link between San Francisco and LA are other milestones. Some of the new entrants in the high-speed rail industry include Denmark, Morocco and Saudi Arabia. On the other hand, Sweden, Scandinavia, the Baltic countries, the Czech Republic, Egypt, Russia, Australia, South Africa, Brazil, Canada, Israel, Iran, Malaysia, Singapore and Indonesia are looking forward to join the bandwagon.
